Recent geological research has dramatically altered our understanding of Stonehenge’s construction. A study published in *Nature* reveals that the Altar Stone, a massive sandstone slab weighing around six tons and central to the monument, is not from the Brecon Beacons in southeast Wales as previously believed. Instead, chemical and mineral analysis shows it originates from the Orcadian Basin in Scotland, approximately 466 miles away. The mineral grains within the stone are between 1,000 and 2,000 million years old, with some around 450 million years old, creating a distinct geological fingerprint linking it to Scottish rocks. This discovery raises significant questions about Neolithic transportation and societal organization. Moving such a large stone over hundreds of miles in 2600 BC suggests advanced maritime and overland logistics, indicating that Neolithic Britons had developed complex trade networks and societal coordination. The possibility of sea transport along the British coast implies a high level of maritime skill and regional connectivity. The findings challenge previous assumptions about the origin of the stones used at Stonehenge, which had been thought to come mainly from Wales. The new evidence suggests that the builders of Stonehenge possessed sophisticated logistical capabilities, possibly involving long-distance maritime routes, to transport stones from distant regions. This insight enhances our understanding of prehistoric Britain’s societal complexity and the cultural connections across regions.
